The full version of PowerDVD 10 Ultra 3D will not remove your PowerDVD Ultra 9. They will run side by side if you want.
If you ever need to remove and install PowerDVD 10 again you will not need PowerDVD Ultra 9 as long as you purchase the full version and not an upgrade.

This is based on my experience.

I dowmloaded thr trail verison Power DVD 10 whats the difference with the paid (BUY) Verison

Thanks

From my experience the Trial is everything you get in the Ultra version. If you buy the lower versions such as deluxe or standard you don't get some options. A lot of people have been stating that Deluxe and Standard do not play blu rays.
A chart that may help:

If you enjoy everything the Trial offered and it worked flawless for you, then the Ultra version is the one that will have all the same features you just tested.

I sent the money everthing went smooth installing Power DVD 10 Ultra.

Whats the patch do

Am using Klipsch Ultra 5.1 with 4 subwoofers X-Fi soundcard the sound is mind blowing

Depends what version you got when you purchased it...
